Hello there, I'm a complete newby to formums so apologies in advance if I make a mistake.
I too have exactly the same problem with the 'Dynamode 4-port PCI-Express Card Superspeed USB3.0 plug n paly'. The drivers on the disc supplied did nothing, so I looked at the chip on the card ' VLI VL805-Q6' and did a search which lead me to the VIA website as mentionied in a previous post one this thread, were I downloaded the 2 driver files, VIA_XHCI_Driver_V4.50A_AP.exe & VIA_XHCI_Driver_V4.40D_AP.exe . The card was recognised after installing the V4.40D. exe program from the VIA website but was not running at 'superspeed' transfer rates of 5Gbps more like 50Mbps with a USB 3.0 HDD! However, when I logged off my PC for the night and logged on the next day the 2 HDD drives plugged into the PCI card were not showing, on checking device manager the yellow ! triangle appeared next to the VIA USB 3 root hub again. Anyone help further with this issue? My system is Win7 Home Premium 64bit.
